Abstract:
A 20-year-old woman presented with bilateral constant positive visual phenomenon since she was 9 years old. The symptoms had been worsening and becoming more intrusive in the last 3 years. Recently she has also had a migrainous episode. All ophthalmic and neurological investigations were normal. Her symptoms met the diagnostic criteria for visual snow. The diagnosis was explained, and the patient was reassured. Ophthalmologists and neurologists need to be aware of this condition to avoid over investigation and worsening of patient anxiety.
